Be it known; that Illinois, have'if .ented ment in Machines-ibn and I do herebydeclare full, clear, and exact d my invention appel-'tain Y i same, reference beingj Shadto' ing drawings forming part of thi in which-4 Figure 1 is-a side elevatlo weavin g wire fabrics embody tion. Fig.2 is a general plan same. Fig. 3 is an enlarge same7 showing that portioj i used in giving form to zigzag i connecting the coils; and Fig; 4 is an enlarged longitudinal central section of the'v device employed in ceiling the wire detached;

Similar letters of reference indicate like parts in the several ig'ure's rof the drawing.

My in vention relates to thatclassof machines employed inthe manufacture of wire fabrics for spring-mattress bed-bottoms, which consist of alternate zigzag wires connected by alternate coils interlocked by passing the coils through each alternate angle of the zigzag wire; and the invention consists in the employment of a revolving 4tapering spindle, in combination with a stationarygrooved mandrel passing around the spindle and adapted to receive and guide the wire whereby the angles of the coil are determined; and in the mechanism employed in holding the wire during the/process of interlocking the coils'into the zigzag wires, as will be more fully. under.- stood hy the description and claims. v

In the drawing, A represents the frame-work of the machine, which is substantially made oi'wood or metal,I and of any requisite' form that will receive the operating parts. E E are face-wheels, which are mounted on transverse shafts journaled in boxes'd d attached to the end C' of the frame. Mounted Von the end of these shafts, opposite to the face-wheels, are gear-wheels F F, which are of unitbrm. diameter, and so arranged as to engage each other, by which means a uniform rotary motion is imparted to lthe wheels E E as power is applied'to the-crank G. Secured within 'theapproximate fac f the wheels E E are shown 1 sto be o l a uniform distance one and the wheels are arranged in such a manner as to bring `=`wheel in the center between e other wheel `as both are unite of the wheels, so as to bring the heelslightly past the pins iu the and toward the center of the same, dotted lines in Fig. 1. J ournaledv f the frame is a shcavc-wheel, m, -rianged as to freely revolve on its .manently attached tothe yupper porhe `end C of the frameis a hollow headsurface of the same.v Loosely secured within this head-block is a hollow sleeve, IM', which is so arrangedasrto freely revolveftherein.

a pulley, D,around which is passed a belt, (not shown,) communicating with an'y suitable motor by which a rotary motion is communicated to the` sleeve. Permanently secured within this sleeve and extendingl paraL lel with the upper surface of the jame is a spindle, f, which is so. arranged as tolrevolve within the head-block. This spindle-extends ontwardfrom` the head-block,and is slightly enlarged at its outer end, as shown in Fig.l 4. Permanently secured within theend of the head-block and around the spindle is a form` ranged as to allow the spindle to revolve freely therein. 'lhe spiral openings .in this mandrel are such as to allow the wire to be coiled to pass loosely through the same. J is an adjustable frame, which is loosely attached to the. bed-timber B of the main frame. This frame J is so arranged as to admit of being moved in the direction of its length, and firmly sewire, a, to be coiled is secured. m( is' sheave-` wheel, which is journaled to the lower portion of the end G of the frame, and so arranged as to freely revolve. I is an adjustable guide, which is so attached to the side of the upper portion of xthe frame as to admit of being ig. 3. These pins are` *andare arranged relative to HM, extending parallel with the upperV Mounted upon the outer end of this sleeve is ing coil or mandrel, L, which is also so ar-V cured at any requisite adjusted point. "f., Mount ed on this frameare spools e c, upon which the y' tion of 'the angles as the moved in' the direction of its length, and firm- 1y secured at the requisite adjustedpoint by a set-screw passing through the same. This guide is provided With an eye, througil. which thelvvire to becoiled loosely passes; The, obl -`ject o this guide is to 'change the position of the wire relative to the openings lin the forming-coil. Permanently attached to the side of the upper portion of this frame are metal plates g g, which forni the holding device H. These plates are each provided with a series of transverse channels formed in theupper edgeras'f shown in Figs. 1`ai1d 2, and are so arranged upon the frame as to bring the channel on each plate in the center between the channelsin. the other plate, as shown in Fig.y 2. The object of these plates is 'to hold the `zigzag Wire in the proper position to allow the coil to pass around the same at Athe intersecto so tighten thecoihas tocausevthe latter'to be drawn throughthe, forming:coil,.:and at the same'vtime so expandthe coil `asito inA .surea uniform diameter ot' the. same regard` Y K less of the spring of the wire.:-

In using-Emy invention, the wire c, from ,which Y ,the zigzag `urines'..are JmaAe, .is'zmund i fx aoundasuitahle spool, (not shown,) and from the spoolit passes aroundrsheave-wheelm upcoils Apass from the specified; Y

Ward through guide t, and between the pins u n of Wheel E E, and as motion is imparted to the Wheel the Wire is drawn from the spool and crimpeduby the engaging of the pins, as

vshown by'dotted-lines, Fig.l 1, by which the Wire is bent in a zigzag form. The Wire is then placed in the holder H, as shown at e, Fig. 2. The wire forming the coil is Wound around spools e e', and from the spools itis passed around. sheave-wheel on upward through the eye of guide l? to and around the spindle, and as the latter is rotated the Wire `is Wound around the spindle, the coil passing through the spiral opening in the itorrning-coil, which determines the angle of vthe coil, and asy the latter passs `from the enlargedcndfof 'the spindle it passes around the zigzag Wires at the intersection of their angles, thus uniting the same, which operation is repeated until the requiredlength .of the fabric is formed. y'

Having' thus described my invention, I claimv 1. The tapered revolving spindle f, in combination with the stationary open coil L, as
